Had you noticed it that while watching videos on YouTube ,we can increase video quality upto 720 p or 1080 P . But , now a days you can watch any video at maximum quality of 480 P . First of all, you might have a question that what is P ? P is nothing than the video pixel resolution . More pixel means more clear video . As we increase pixel , quality of video also increase. As , you know in 144P , the video quality is very low so it looks blur . As we increase upto 720 p we get hd and clear video.
The question might arise in your mind that why YouTube doesn't provide quality of 720p or 1080 p . From last six months , we are facing crisis of Corona Virus. Due to it , for prevention we stop all the system by lockdown . Due to lockdown , we don't have chance to move from home . So all people has only means of entertainment is their mobile . YouTube is best source of entertainment and if people watch video in best 720 to 1080 P ,they exhaust their data with in 3 to 4 hour . To save many people's data , YouTube took action and made maximum quality of video 480 P . Work from home is also started and we want more data . In watching videos , if our more data exhaust , then we might arises question. So for People , YouTube done it
